Actually it won't, as there is relatively little ocean-side property to affect in the first place. With the exceptions of a few coastal towns like Scheveningen, property development is illegal along the coast as it would hinder future coastal protection. Consequently private ownership of coastal area is also unheard of here. Because there are no buildings on them, the most cost effective way of improving our coastal defences is relatively easy and low-tech: just add more sand to the dunes and beaches.
